Hallo

I want to know more about a battle near Audierne on 23.08.1944. The british cruiser HMS Mauritius, the british destroyer HMS Ursa and the canadian destroyer HMCS Iroquois were engaged with boats of the 7. Vorpostenflottille.
As far i know the following german boats were sunk: V-717, V-727, V-729 and V-730

Are their more boats sunk or damaged in this battle? What was the civil name and flag of this ships before they became german Vorpostenboote. Information about casualties are available ?

Thank you
Axel
